Introducing one and signing off on one are two completely different things. That also leaves plenty of wiggle room for banning all manner of items that are related to those weapons. It leaves open the registration of the weapons and their owners, leaves open the possibility of punitive taxes, the legality of keeping it at home... ad nauseum, ad infinitum.
Anyway if all the headline implies is true, great. I do not trust them now, and likely will not trust them in the future. Gun grabbers, Democrat and Republican alike treat this issue as a religion, logic and fact are not to be part of the discussion, end results are all that matter. They are willing to eat the elephant one bite at a time.
